I think your JSON should be like this:
[
{"Id":1,"Title":"Vacation","HourTypeCodes":[
{"Id":"05","Title":"VACPOLICE/FIRE",},
{"Id":"04","Title":"VACATION"},
{"Id":"62","Title":"VACATION HOURS PURCHASED"},
{"Id":"60","Title":"VACATION SELL BACK"}
]
},
{"Id":2,"Title":"Holiday","HourTypeCodes":[
{"Id":"08","Title":"HOLIDAY"}
]
},
{"Id":3,"Title":"Floating Holiday","HourTypeCodes":[
{"Id":"09","Title":"FLOATING HOLIDAY"}
]
}
]
That would be syntactically correct. However, whether or not it is fit for purpose I am not sure. The top level is an array of objects. What is
"key" when it is retrieved with $(this).prev("input").val(); ?
Is it an array index or is it a value of the "Id" property in each of the objects? If it is the latter, then you don't really have a nice efficient way of getting to the object you want, unless the Id property is always the array index + 1 ?
For example, if "key" contained "1", I would be able to traverse the HourTypeCodes like this:
$.each(jsondata[key-1].HourTypeCodes,function(i,item){ });

Strange forum for a JSON/jQuery question - but anyhow, the JSON you have posted is syntactically incorrect. Is that just a typo?
Can you post all the significant code please, rather than a snippet, and explain a bit more fully what you are trying to do.
Thanks

Subject: [WEB400] Navigating JSON sub-arrays dynamically
I am using JSON and jQuery to dynamically populate a parent/child dropdown
lists. I have it working to fill the parent drop down and have the child
drop down filling with the same parent data. How do I loop through the sub
array of the selected value from the parent?
My "each" line (key is the value from my parent DDL:
var key = $(this).prev("input").val();
$.each(jsondata.Id[key].HourTypeCodes, function(i, item) {
My JSON
[{"Id":1,"Title":"Vacation","HourTypeCodes":[{"Id":"05","Title":"VAC
POLICE/FIRE",},{"Id":"04","Title":"VACATION"},{"Id":"62","Title":"VACATION
HOURS PURCHASED"},{"Id":"60","Title":"VACATION SELL BACK"}]},
{"Id":2,"Title":"Holiday""HourTypeCodes":[{"Id":"08","Title":"HOLIDAY"}]},
{"Id":3,"Title":"Floating
Holiday","HourTypeCodes":[{"Id":"09","Title":"FLOATING HOLIDAY"]}]
What am I doing wrong?
